Suggested Water Quality Testing for Private Wells

The purpose of this document is to identify those water quality contaminants that the Department
of Environmental Services (DES) recommends be tested in private wells. These contaminants are
generally related to New Hampshire's geology and types of land use.
State, Town, and Lender Requirements

There is no state requirement for testing the water quality of private wells; accordingly, the
following information is offered only for educational purposes. State law (RSA 477:4-c),
however, requires that certain information concerning a home’s water system be disclosed to a
purchaser, including an unsatisfactory water test. The term "unsatisfactory water test" is not
defined in statute.

Since there are no state water quality testing requirements, a few towns, primarily in southern
New Hampshire, have identified lists of required water quality test parameters. Such town
requirements are typically expressed as the obligation to test for certain contaminants, but not
necessarily to achieve compliance. This testing is typically associated with the building code
requirements for new construction, such as a certificate of occupancy. Please check with your
town to see if water quality testing of a private well is required and under what circumstances.
The Veterans Administration (VA), Federal Housing Administration (FHA) and many banks
require some water quality testing when writing a mortgage. However, their requirements are not
consistent, and historically there has been more emphasis on factors that pertain to aesthetics
than factors that pertain to health.



LIST OF SUGGESTED CONTAMINANTS
The list of contaminants below has been prepared after a review of the extensive records of
DES's public water supply program. Although more test parameters could be added, this list
provides a reasonable balance between the high cost of extensive testing and the relatively low
cost of testing for only those contaminants that are more commonly found in New Hampshire.
If contaminant(s) are found, please reference the DES fact sheet(s) for that particular
contaminant at www.des.nh.gov/wseb then link to "fact sheets" under "Publications" and see fact
sheet WD-WSEB-2-5, entitled "Considerations When Purchasing Water Treatment Equipment."

ADDITIONAL TESTING BASED ON THE ANALYSIS OF THE WELL'S LOCATION
OR THE RESULTS OF THE FIRST ROUND OF WATER QUALITY TESTING
Organics Testing

There are two groups of organic contaminants, volatile organic compounds (VOC) and
synthetics organic compounds (SOC). Only VOCs are generally recommended for testing. All
contaminants in the organics group come from manmade sources. Laboratory testing for these
contaminants is expensive. There are approximately 60 organic contaminants in these two
categories.

Volatile Organic Compounds (VOC). The DES recommended test for volatile organic
chemicals (VOC) targets gasoline compounds, including MtBE, and industrial solvents.
Repeat testing frequency for organics depends on a site review of the area near and uphill
of your well identifying past or present land uses that make such contamination possible.
Examples of some, but not necessarily all, activities that would produce these
contaminants include heavy industrial or commercial activity, past or present landfills,
buried chemical or hydrocarbon storage tanks. Some other water quality factors important
in judging whether VOC organics testing may be necessary include:
- If there is taste or odor in the water supply, particularly if characterized as "strange or
unusual" but not including hydrogen sulfide.

- If state and local records identify hazardous waste sites and other contamination areas
nearby or upstream of your well, then test for VOCs and SOCs as appropriate.
Synthetic Organic Contaminants (SOC). Testing for the remaining organics, often characterized
as pesticides and herbicides, is very expensive, costing from $250 –$500 per sample. Although
DES does perform such water quality testing, these tests are available only to public water
systems. Some other water quality factors important in judging whether pesticides/herbicide
organics testing may be necessary include:

- Elevated nitrate/nitrite concentrations may indicate past agricultural activity where
pesticides and/or herbicides may have been used.

- If there is taste and odor in the water supply, particularly if characterized as "strange or
unusual" but not including hydrogen sulfide, then test for VOCs.

- If state and local records identify hazardous waste sites and other contamination areas
nearby or upstream of your well, then test for VOCs and SOCs as appropriate.
Gross (Beta) Screen Testing



FREQUENCY OF TESTING
Water quality in wells is normally stable and, if varying, the change occurs slowly. Thus the
interval between water quality samples taken from a properly constructed well, located in a safe
area, can generally be in terms of years.The NH dept of enviromental servicrs can recomend frequancy of tests, www.des.nh.gov.

These frequencies are appropriate for wells
in rural areas believed to be free of groundwater contamination sites.
There are a variety of conditions that would prompt modifications of these average monitoring
frequencies. Some include:

Areas of Higher Contaminant Possibility. In more built-up areas and those with known
groundwater contamination sites, increasing the sampling frequency for appropriate
contaminants is warranted. In these situations the frequency for each contaminant would be
determined individually based on an assessment of the well type, contaminant type, and level of
health risk.

Proper Well Construction. DES recommends that wells not be sampled for bacteria unless
their construction is excellent. Poor well construction can lead to high bacterial counts. Proper
well construction is detailed in fact sheets WD-WSEB-1-2 through 1-6. DES recommends taking
a bacterial test after any well repair, and after every pump or plumbing modification, but only
after substantial flushing to clean the area where work occurred.

Sample Timing and Location. Where treatment is already installed, DES recommends that the
sample be taken of the treated water just before the treatment system is scheduled to be
regenerated. Where you desire to have a record of the baseline quality of your well water,
additional testing should be done of the untreated water. Such testing provides a historical and
official record of your well’s quality. This historical data is often valuable when contending that
contamination of your well has occurred by the recent activities of others.

Higher Concentrations. Where any health parameter is greater than 75 percent of the public
drinking water maximum contaminant level (MCL), more frequent sampling should be
performed until one can reasonably conclude that the concentration of that contaminant is
reliably and consistently below the MCL. Suggested accelerated sampling frequencies are shown
in the extreme right hand column of page 2 for contaminant situations that have stabilized.
This column is identified with the heading "greater than 75 percent." Where the contaminant
level in your well is unstable or unknown, much more frequent testing is warranted. This testing
frequency would be individually determined based on the specifics of the area and the
contaminant risk.

Variation in Quality. Where the water quality in a supply varies after a heavy rain or when you
have experienced a rapid and unexplained substantial change in quality from the past long term
performance of that well, we suggest weekly or monthly sampling for bacteria, and possibly
other parameters, until the condition stabilizes. Heavy precipitation tends to mobilize bacteria
and thus highlight conditions of poor well construction or inadequate soil filtration. Thus
bacterial sample(s) should always be taken after a heavy rainstorm.
